The Real Cost of Quitting Your Job to Be a Caregiver

Why the Social Security hit is the part people miss

Social Security's benefit formula averages your indexed earnings across your 35 highest-earning years (the AIME — Average Indexed Monthly Earnings). If you don't have 35 years of earnings yet, or the leave years would otherwise have counted among your top 35, every $0 year you add to that average permanently drags down your monthly benefit — not just during the leave, but for every month you collect Social Security afterward. We ran a $65,000/year earner through the SSA's own bend-point formula for a 2-year leave: their Primary Insurance Amount (PIA) drops from an estimated benefit at full earnings history to a measurably lower one, and that gap repeats every single month of retirement.

We checked the 2025 bend points directly against the SSA's published formula: 90% of the first $1,226 of AIME, 32% of the amount between $1,226 and $7,391, and 15% above that. It's a progressive formula, which means lower earners lose a larger percentage of their benefit per dollar of reduced AIME than high earners do — caregiving leave is regressive in its Social Security impact.

How the math works

1. Lost wages = annual salary × years of leave. No growth applied — the money never existed to invest.
2. Lost employer match = (salary × match% × years of leave), modeled as a lump sum at the leave's midpoint, then compounded at your assumed return to retirement.
3. Social Security AIME impact = your salary ÷ 12 treated as a flat 35-year career average; the leave years replace what would otherwise count, diluting the 420-month average.
4. PIA before/after = SSA's bend-point formula (90% / 32% / 15%) applied to the AIME before and after the leave.
5. Lifetime Social Security loss = monthly PIA difference × 12 × expected years collecting benefits.

Where this calculation breaks

• You already have 35 high-earning years banked.If you're later in a long, high-earning career, leave years might not displace a top-35 year at all — your real Social Security hit could be much smaller than this worst-case estimate shows.
• Partial, reduced-hours work isn't modeled.This tool assumes all-or-nothing leave. Dropping to part-time or reduced hours instead of fully quitting changes every number here proportionally, but not linearly (benefits and matches often have thresholds).
• Raises and promotions you might have gotten aren't counted.Lost wages use your current salary flat across the leave — if you'd realistically have been promoted or raised during that window, the true lost-wages figure is higher.
• A caregiver credit or spousal benefit might offset part of this.Some pensions and a small number of state programs offer caregiver credits; spousal Social Security benefits (up to 50% of a spouse's PIA) can also partially offset an individual's own reduced benefit. Neither is modeled here.

What to actually do

1. Run your real numbers here before deciding to leave a job — the total is almost always larger than the salary alone suggests.
2. Check whether your employer offers FMLA (unpaid, job-protected) or paid family leave instead of a full resignation — a temporary leave preserves both the job and the retirement-match continuity.
3. If reduced hours are an option instead of a full exit, model that scenario too — the Social Security and match hits shrink roughly proportionally.
4. Check your state for paid family leave programs (a growing number of states now offer partial wage replacement for caregiving leave).
5. If you do take the leave, consider contributing to an IRA during that period if you have any income at all — it won't offset the Social Security hit, but it rebuilds some of the retirement gap.
